Cylinder Head Temp
I have search but haven't found anything. I have a 2016 Heritage and would like to know what is normal head temperature. Mine is running a 330 to 348 degrees. Is this normal?

You can in heavy traffic hot day see 360. No big deal to the bike it may bother you a bit.

I do not have a way to measure but today (97 out with index 109) my ole 96 got a wee bit hot for sure. I am thinking Love Jugs in my future. I have to put the Captain Itch bibs on as well....had em in the shop and forgot to put em back on after battery swap. My wife's 88 with the Vance n Hines longshots got really hot too but she never complains.

With the oil tank right under the seat it certainly adds to the amount of felt heat to the rider .. Yes our Crotch cooler will make your ride more comfortable ..

High Heat ..???
Damn !!!
That kind of heat will not hurt the motor itself ...but heat cycling all the orings in the motor at those temp's will take a toll on them ...they will get hard and dry , crack ...etc...the rubber umbrella valves will cease working right ... this will be evident by the oil leaks that start to show up ...seeping oil at the base gaskets, pushrod tubes and valve covers ...
but then again ...there are people here that say the high heat is just the nature of the beast ...and that it don't hurt anything....
even harley knows (but will never say ) that there's a heat problem , (which is way they are trying water cooling too ...IT IS AN AIR COOLED MOTOR..you must keep air moving over it !!! it's not like your car !!!

I know you're not trolling, but damn. You make it sound like every harley is stopped by the side of the road in flames.
Yes, they're not water cooled. But they sent one to hell and it came back smilin!
No harm, no foul. Peace!
